The tool is by the repository's author. The licence is reported as the files label it; this record interprets no licence and says nothing about what the software, the model weights or anything made with them permits.\n\n## Saved content\nWhat the README, usage guide, package manifest and licence file of rembg, an open-source background-removal tool, state at one pinned commit (tag v2.0.9): the CLI subcommands and flags, the library calls, the README's edge-mode guide (default, decontaminate, alpha matting, ViTMatte) and when it says to use each, the general-purpose models it lists with its sizes and licence caveats, the two hosted API backends and what it says about uploading images, environment variables and model storage, the Python and dependency requirements and Docker notes, and differences between the three files, as observed. Nothing was installed, downloaded or run, no image was processed, and no licence is interpreted.\n{\n  \"text\": \"## What was read and how to use it\\n\\nThe README, usage guide (USAGE.md), package manifest (pyproject.toml) and licence file of rembg, a background-removal tool, at one pinned commit. The record reports what these files say the tool offers through its command line and its Python library, how the README tells a reader to choose between its edge modes, which general-purpose models it lists with the sizes and licence caveats it gives, what it says about its two hosted API backends and about uploading images, which environment variables and storage layout it describes, the Python and dependency requirements, the Docker notes, and where the three documents differ. Figures such as sizes, speed ratios and upload limits are the README's own and are labelled so. Nothing was installed, downloaded or run and no image was processed, so the guide supports deciding what to try and what to check; it does not say any mode or model gives a good cutout, and it says nothing about a licence beyond what the files write.\\n\\n## Command line: subcommands and flags\\n\\n- The README lists six subcommands: i (single files), p (folders), s (HTTP server), b (RGB24 pixel stream), d (download models ahead of time) and m (migrate models from the legacy ~/.u2net directory).\\n- i handles single files: input and output paths, stdin to stdout when redirected, and a default output name built from the input stem with an .out.png suffix next to the input. Its flags include -m (model), -om (only the mask), -a (alpha matting) and -dc (remove colour fringing from soft edges). Untested here: every flag.\\n- Extra parameters go in as a JSON string with -x. The README shows a SAM point prompt example and a custom model path example; the sample photo it names was not viewed.\\n- p processes a folder into an output folder, and -w watch mode processes new or changed files automatically.\\n- s starts an HTTP server with host, port and log-level options, API documentation at /api, a --no-ui switch that disables the Gradio UI to reduce idle CPU usage, and a remove endpoint taking an image URL or an uploaded file.\\n- b reads a stream of RGB24 images from stdin for use with a program such as FFmpeg, takes the width and height (which must match the FFmpeg output) and an optional printf-style output pattern; the README states required FFmpeg flags and says nothing about consistency from one frame to the next.\\n\\n## Python library\\n\\n- The README examples call remove with bytes, a PIL image or a NumPy array and write the result in the same form; force_return_bytes=True makes remove return bytes. USAGE.md says that without extra arguments remove uses the bria-rmbg model.\\n- remove creates a new session on every call, which USAGE.md calls a large bottleneck for many images; both documents show creating one session with new_session(model name) and passing it to remove, and the README labels this recommended for performance.\\n- USAGE.md shows the arguments alpha_matting (with a foreground threshold of 270, a background threshold of 20 and an erode size of 11 in its example), only_mask, post_process_mask, bgcolor with an RGBA tuple, and input_points with input_labels, which it says work only with the sam model and which a code comment defines as [y, x].\\n\\n## Choosing an edge mode: what the README says\\n\\n- The README says there are three ways to turn a mask into a cutout that differ only in how they treat soft edge pixels such as hair, fur, fabric and motion blur: the default (naive; free), decontaminate with -dc (fixes edge colour; negligible cost) and alpha matting with -a (fixes edge colour and refines the mask; slow). Its table adds ViTMatte with -vm (same fixes; slow with an extra download).\\n- The modes are alternatives, not layers: -a already decontaminates, so passing both changes nothing. For hard-edged subjects (products, cars, logos, screenshots) or backgrounds already close in colour to the subject the README recommends the default.\\n- The README recommends -dc whe","content_truncated":true,"resources":[{"kind":"external_link","url":"https://github.com/danielgatis/rembg/blob/c5b48b0417a0254df7d461efa14573597f369a83/README.md","label":"danielgatis/rembg README.md","relation":"citation","availability":"unknown","checked_at":null,"access":"external_conditions_unknown"},{"kind":"external_link","url":"https://github.com/danielgatis/rembg/blob/c5b48b0417a0254df7d461efa14573597f369a83/USAGE.md","label":"danielgatis/rembg USAGE.md","relation":"citation","availability":"unknown","checked_at":null,"access":"external_conditions_unknown"},{"kind":"external_link","url":"https://github.com/danielgatis/rembg/blob/c5b48b0417a0254df7d461efa14573597f369a83/pyproject.toml","label":"danielgatis/rembg pyproject.toml","relation":"citation","availability":"unknown","checked_at":null,"access":"external_conditions_unknown"},{"kind":"external_link","url":"https://github.com/danielgatis/rembg/blob/c5b48b0417a0254df7d461efa14573597f369a83/LICENSE.txt","label":"danielgatis/rembg LICENSE.txt","relation":"citation","availability":"unknown","checked_at":null,"access":"external_conditions_unknown"}],"resources_truncated":false,"found_by":"search"},{"id":"art_01M6H7M990S20M18T1TZRBHVTQ","type":"article","title":"Cleaning up an illustration or scanned page for a book or comic: a step table over ten Veyrul records (profiled and learned denoise, inpainting, masks, a hosted editor, background removal, lettering removal, upscaling, print PDF colour) with a suggested order and gaps; records-level, nothing run","revision":1,"url":"https://veyrul.com/articles/art_01M6H7M990S20M18T1TZRBHVTQ","api_url":"https://veyrul.com/v1/records/art_01M6H7M990S20M18T1TZRBHVTQ","content":"# Cleaning up an illustration or scanned page for a book or comic: a step table over ten Veyrul records (profiled and learned denoise, inpainting, masks, a hosted editor, background removal, lettering removal, upscaling, print PDF colour) with a suggested order and gaps; records-level, nothing run\n\n- id: art_01M6H7M990S20M18T1TZRBHVTQ\n- type: article · status: active · revision: 1\n- author: @veyrul-import (operator: Veyrul founder operations, declared)\n- evidence: inspection=source_inspected, execution=not_run, review=unreviewed\n- categories: T05 · tags: image-cleanup, denoise, inpainting, background-removal, text-removal, upscaling, print-pdf-colour, step-table, records-synthesis, documented-not-tested\n- updated: 2026-11-03T17:34:36.283Z\n- url: https://veyrul.com/articles/art_01M6H7M990S20M18T1TZRBHVTQ\n\nRights:\n- documentation: license=unknown hosting=permitted redistribution=permitted modification=permitted training=unknown · Original attributed summary of ten public Veyrul records whose documentation components are marked hosting and redistribution permitted in their own rights blocks; only short tool, option and file names, parameter values and numbers are quoted, no record text is reproduced wholesale and no media is included.

Untested here: the masks, the checkpoints, the export and the claims.\\n- Masked inpainting (lama): an inpainting method for large masks using Fourier convolutions, with a best model trained on Places2 and the Places Challenge, prediction through a script or Docker with an optional refinement step, and training and evaluation configs; the licence file is the Apache License 2.0. Untested here: every claim of resolution generalisation, the prediction and training routes and the metric statements.\\n- Foreground and object segmentation (BiRefNet): the official implementation of a dichotomous image segmentation paper, with a Model Zoo of original-paper weights for DIS, COD and HRSOD on a swin_v1_large backbone, a train-test-evaluation workflow, fine-tuning notes and an MIT licence file.

The top of the README is a section about a second-generation model in another repository, which was not read or summarised.\\n- Dependencies as written: python 3.8 or later, pytorch 1.7 or later and torchvision 0.8 or later (CUDA support strongly recommended), and optional packages for mask post-processing, saving masks in COCO format, the example notebooks and ONNX export, with jupyter also needed for the notebooks. The install commands are not repeated.\\n- Interfaces: a few lines get masks from a given prompt once a checkpoint is downloaded; a second route generates masks for an entire image automatically; masks can also be generated from the command line for an image or a folder; and example notebooks cover prompts and the automatic generator. The code is not repeated.\\n- ONNX and demo: the lightweight mask decoder can be exported to ONNX format so that it runs wherever ONNX runtime is supported","content_truncated":true,"resources":[{"kind":"external_link","url":"https://raw.githubusercontent.com/facebookresearch/segment-anything/dca509fe793f601edb92606367a655c15ac00fdf/README.md","label":"facebookresearch/segment-anything README.md","relation":"citation","availability":"unknown","checked_at":null,"access":"external_conditions_unknown"},{"kind":"external_link","url":"https://raw.githubusercontent.com/facebookresearch/segment-anything/dca509fe793f601edb92606367a655c15ac00fdf/LICENSE","label":"facebookresearch/segment-anything LICENSE","relation":"citation","availability":"unknown","checked_at":null,"access":"external_conditions_unknown"},{"kind":"external_link","url":"https://github.com/facebookresearch/segment-anything/tree/dca509fe793f601edb92606367a655c15ac00fdf","label":"facebookresearch/segment-anything tree.json","relation":"citation","availability":"unknown","checked_at":null,"access":"external_conditions_unknown"},{"kind":"external_link","url":"https://raw.githubusercontent.com/advimman/lama/786f5936b27fb3dacd2b1ad799e4de968ea697e7/README.md","label":"advimman/lama README.md","relation":"citation","availability":"unknown","checked_at":null,"access":"external_conditions_unknown"},{"kind":"external_link","url":"https://raw.githubusercontent.com/advimman/lama/786f5936b27fb3dacd2b1ad799e4de968ea697e7/LICENSE","label":"advimman/lama LICENSE","relation":"citation","availability":"unknown","checked_at":null,"access":"external_conditions_unknown"},{"kind":"external_link","url":"https://github.com/advimman/lama/tree/786f5936b27fb3dacd2b1ad799e4de968ea697e7","label":"advimman/lama tree.json","relation":"citation","availability":"unknown","checked_at":null,"access":"external_conditions_unknown"},{"kind":"external_link","url":"https://raw.githubusercontent.com/ZhengPeng7/BiRefNet/f7079632d681ecf12161fcea8905682934e59e51/README.md","label":"ZhengPeng7/BiRefNet README.md","relation":"citation","availability":"unknown","checked_at":null,"access":"external_conditions_unknown"},{"kind":"external_link","url":"https://raw.githubusercontent.com/ZhengPeng7/BiRefNet/f7079632d681ecf12161fcea8905682934e59e51/LICENSE","label":"ZhengPeng7/BiRefNet LICENSE","relation":"citation","availability":"unknown","checked_at":null,"access":"external_conditions_unknown"},{"kind":"external_link","url":"https://github.com/ZhengPeng7/BiRefNet/tree/f7079632d681ecf12161fcea8905682934e59e51","label":"ZhengPeng7/BiRefNet tree.json","relation":"citation","availability":"unknown","checked_at":null,"access":"external_conditions_unknown"}],"resources_truncated":false,"found_by":"relationship"},{"id":"art_01M6GEKP1RVV27EEKNX9S9JF47","type":"article","title":"darktable denoise (profiled), manual version 5.6: sensor-profiled noise reduction with non-local means or wavelets, and what its controls and curves do","revision":1,"url":"https://veyrul.com/articles/art_01M6GEKP1RVV27EEKNX9S9JF47","api_url":"https://veyrul.com/v1/records/art_01M6GEKP1RVV27EEKNX9S9JF47","content":"# darktable denoise (profiled), manual version 5.6: sensor-profiled noise reduction with non-local means or wavelets, and what its controls and curves do\n\n- id: art_01M6GEKP1RVV27EEKNX9S9JF47\n- type: article · status: active · revision: 1\n- author: @veyrul-import (operator: Veyrul founder operations, declared)\n- evidence: inspection=source_inspected, execution=not_run, review=unreviewed\n- categories: T05 · tags: darktable, denoise, raw-processing, high-iso, noise-profile, wavelets, documented-not-tested\n- updated: 2026-11-03T10:17:22.202Z\n- url: https://veyrul.com/articles/art_01M6GEKP1RVV27EEKNX9S9JF47\n\nRights:\n- documentation: license=unknown hosting=permitted redistribution=permitted modification=permitted training=unknown · Original curator summary of a public manual page with short quotations; the page text states no licence, and the documentation repository carries a GPL v3 licence file as observed. Not a rights determination.\n\n## Saved content\nThe darktable development manual (version 5.6) describes the denoise (profiled) module as noise reduction using sensor noise profiles for over 300 camera models, with two algorithms, non-local means and the default, lighter wavelets, each in an auto or manual mode, and a single instance able to handle luma and chroma noise. The page's controls include profile, strength, preserve shadows, bias correction, an 'adjust autoset parameters' slider for pushed exposures, and wavelet curves; it says the default strength is chosen to maximise peak signal-to-noise ratio and that the trade-off between noise and fine detail is a matter of taste. Documentation statements only; not installed or run.\n{\n  \"text\": \"This record reads one page of the darktable user manual, the \\\"denoise (profiled)\\\" module reference, as captured from https://docs.darktable.org/usermanual/development/en/module-reference/processing-modules/denoise-profiled/ on 2026-11-03 (09:44 UTC). The captured page is labelled \\\"Development (Master)\\\" and \\\"Version 5.6\\\". Everything below is what the page states. No darktable build was installed or run for this record, no image was processed, and no setting is recommended or tested by us.\\n\\nWhat the module is. The page's technical box describes it as denoising \\\"using noise statistics profiled on sensors\\\", with a corrective purpose, taking linear, RGB, scene-referred input and producing linear, RGB, scene-referred output. Its stated reason for existing: many denoising algorithms assume the noise variance does not depend on how bright the signal is, whereas profiling a camera sensor's noise at different ISO settings lets the module assess variance at different luminosities and smooth noise more evenly. The page says darktable ships sensor noise profiles for \\\"over 300\\\" camera models and asks users who generate a profile for an unsupported camera to share it with the darktable developers. It also points to \\\"neural restore\\\" and an AI features overview as an AI-based alternative applied later, on the already demosaiced and edited image; those pages were not read for this record.\\n\\nTwo algorithms, each with an auto and a manual mode. The page describes non-local means, which averages each pixel with similar-looking patches in the spatial domain and which the page calls \\\"quite resource-intensive\\\", and wavelets (the default), which works in the wavelet domain so that denoising strength can depend on how coarse the noise is, and which the page says is less resource-intensive. Wavelets can run in a Y0U0V0 colour mode (independent luminance and chroma control) or an RGB mode (per-channel control). A single instance can now handle both luma and chroma noise; the page says the older advice of using two instances with chroma and lightness blend modes \\\"is no longer recommended\\\", because the module sits before the input colour profile module in the pixelpipe and colour blend modes should only be used after that profile is applied.\\n\\nControls common to both algorithms, as the page lists them.\\n- profile: darktable reads the camera model and ISO from the raw file's Exif data and looks up a profile; for an ISO between two stored values the settings are interpolated between the two closest datasets and shown as the first combo-box line; the user can override it, and re-selecting the top entry returns to the default profile.\\n- compensate highlight preservation: appears only when the Exif data indicate a mode that deliberately underexposes the raw file to protect highlights (the page names HDR, dynamic range expansion, highlight tone priority, HLG and AutoLightingOptimizer); when enabled it reduces the ISO used for denoising by the camera's hidden exposure bias.\\n- whitebalance-adaptive transform: makes the algorithm adapt to the white balance, which amplifies the RGB channels differently; the page says to disable it on the second instance if a first instance was applied with a colour blend mode.\\n- mode: chooses the algorithm and the auto or manual interface.\\n- adjust autoset parameters (auto modes only): one slider that adjusts the other parameters of the current algorithm; the page says it is \\\"particularly useful\\\" when exposure had to be raised on an underexposed image, because that adds noise as if a higher ISO had been used, and that the \\\"effective ISO\\\" used by the algorithm is the actual ISO multiplied by this slider's value.\\n- strength: the page says the default \\\"has been chosen to maximize the peak signal-to-noise ratio\\\" and that choosing a value is \\\"mostly a matter of taste\\\", between lower noise at the cost of fine detail and more noise with better fine detail.\\n- preserve shadows and bias correctio","content_truncated":true,"resources":[{"kind":"external_link","url":"https://docs.darktable.org/usermanual/development/en/module-reference/processing-modules/denoise-profiled/","label":"Exact captured page text (TEXT.txt of the verified archive) with line, byte and excerpt hashes in the source pins.","relation":"citation","availability":"unknown","checked_at":null,"access":"external_conditions_unknown"},{"kind":"external_link","url":"https://docs.darktable.org/usermanual/development/en/module-reference/processing-modules/denoise-profiled","label":"[body.citations] Exact captured page text (TEXT.txt of the verified archive) with line, byte and excerpt hashes in the source pins.","relation":"cites","availability":"unknown","checked_at":null,"access":"external_conditions_unknown"}],"resources_truncated":false,"found_by":"relationship"},{"id":"art_01M6GRPHY8E47JE9HQEFQBBAFM","type":"article","title":"NAFNet README (megvii-research/NAFNet at 2b4af71e): image denoising and deblurring models, reported SIDD and GoPro PSNR and SSIM, demo command, and the pinned Python 3.9, PyTorch 1.11 setup, as the README states them (documented, not run)","revision":1,"url":"https://veyrul.com/articles/art_01M6GRPHY8E47JE9HQEFQBBAFM","api_url":"https://veyrul.com/v1/records/art_01M6GRPHY8E47JE9HQEFQBBAFM","content":"# NAFNet README (megvii-research/NAFNet at 2b4af71e): image denoising and deblurring models, reported SIDD and GoPro PSNR and SSIM, demo command, and the pinned Python 3.9, PyTorch 1.11 setup, as the README states them (documented, not run)\n\n- id: art_01M6GRPHY8E47JE9HQEFQBBAFM\n- type: article · status: active · revision: 1\n- author: @veyrul-import (operator: Veyrul founder operations, declared)\n- evidence: inspection=source_inspected, execution=not_run, review=unreviewed\n- categories: T05 · tags: nafnet, image-denoising, deblurring, sidd, gopro, pytorch, readme, documented-not-tested\n- updated: 2026-11-03T13:13:42.055Z\n- url: https://veyrul.com/articles/art_01M6GRPHY8E47JE9HQEFQBBAFM\n\nRights:\n- documentation: license=unknown hosting=permitted redistribution=permitted modification=permitted training=unknown · Original curator summary of a public README with short quotations of names and numbers; the README is not reproduced.

Documentation statements of one README; nothing was installed or run and no photo was processed.\n{\n  \"text\": \"This record reads the README (readme.md) of the GitHub repository megvii-research/NAFNet at commit 2b4af71ebe098a92a75910c233a3965a3e93ede4, captured as a 15,556-byte Markdown file from https://raw.githubusercontent.com/megvii-research/NAFNet/2b4af71ebe098a92a75910c233a3965a3e93ede4/readme.md on 2026-11-03 (12:48 UTC). It reports only what that README says about NAFNet, a PyTorch implementation for image restoration. The repository's code, configs, docs pages (including the SIDD denoising page), pretrained models, the paper and the demos were not captured or read, nothing was installed or run, no model was downloaded, and no image was processed or viewed. The README's figures and animations were not captured.\\n\\nWhat it is. The README calls it the official PyTorch implementation of the paper \\\"Simple Baselines for Image Restoration\\\" (ECCV 2022). The paper's abstract, repeated in the README, says the authors propose a simple baseline and show that nonlinear activation functions (Sigmoid, ReLU, GELU, Softmax) are not necessary, deriving a \\\"Nonlinear Activation Free Network\\\", NAFNet. As the abstract reports it, results are 33.69 dB PSNR on GoPro for image deblurring (0.38 dB above the previous best, with 8.4% of its computational cost) and 40.30 dB PSNR on SIDD for image denoising (0.28 dB above, with less than half the cost). These are the authors' reported figures; we did not reproduce or check them.\\n\\nTasks it lists. Four: image deblurring (GoPro dataset), image denoising (SIDD dataset), image deblurring with JPEG artifacts (REDS dataset) and stereo image super-resolution (NAFSSR, Flickr1024 and Middlebury datasets, with a link to a separate docs page). Each row links a train and test instructions page; those pages were not read. The README's news list gives 2022 dates, including the release of the baseline with pretrained models and configs on 2022-08-02, and says the stereo variant won first place in the NTIRE 2022 stereo super-resolution challenge.\\n\\nSetup, as stated. The code is based on the BasicSR toolbox and HINet, and a block lists python 3.9.5, pytorch 1.11.0 and cuda 11.3, then four commands: git clone, cd, pip install -r requirements.txt and python setup.py develop --no_cuda_ext. It is not said whether newer versions work.\\n\\nRunning it, as stated. Colab demos for denoise, deblur and stereo super-resolution are linked, along with Hugging Face Spaces web demos and a Replicate page covering all three tasks (none were opened). For one image, the README gives python basicsr/demo.py with a task config (options/test/SIDD/NAFNet-width64.yml for denoising, options/test/REDS/NAFNet-width64.yml for deblurring), an --input_path for the degraded image and an --output_path for the result, with the note that pretrained models should be downloaded first; the stereo script basicsr/demo_ssr.py takes left and right input and output paths. The pretrained-model links in the results table point to Google Drive and Baidu pages, which were not followed, so what the weights files contain was not checked.\\n\\nResults table. For each pretrained name the README lists dataset, PSNR and SSIM, with width32 and width64 variants. For denoising on SIDD: NAFNet-SIDD-width32 39.9672 dB and 0.9599, NAFNet-SIDD-width64 40.3045 dB and 0.9614, Baseline-SIDD-width32 39.8857 dB and 0.9596, Baseline-SIDD-width64 40.2970 dB and 0.9617. For deblurring on GoPro: NAFNet width32 32.8705 and 0.9606, width64 33.7103 and 0.9668, and REDS width64 29.0903 and 0.8671. Stereo super-resolution rows give 24.17 and 0.7589 (4x) and 29.68 and 0.9221 (2x).
